A versatile solution for indoor and outdoor structural flooring with Hardie™ Deck

Hardie™ Deck is a low-maintenance alternative to timber decking, made from Hardie™ fibre cement.

Unlike timber, Hardie™ Deck is resistant to damage from moisture and termites. It is also deemed non-combustible making it an ideal bushfire zone deck or fire pit deck. With concealed screws and solid, splinter-free boards, Hardie™ Deck feels smooth and safe and under bare feet.

With adequate cross-flow ventilation, Hardie™ Deck can be used as low as 150mm from the ground with its concealed fixing system that integrates drainage and improves ventilation.

Durable, low-maintenance decking with a modern look

Hardie™ Deck combines specially machined 19mm thick fibre cement decking boards with a unique aluminium fast-track system that conceals all fixings for a clean, modern finish. The jointing system includes an anodised aluminium base jointer that is screwed to the framing joists, and a powder-coated snap-in top strip that covers the screw heads and creates a continuous contrasting line between the boards once painted.

The Hardie™ Deck system comprises three main components:

  • Hardie™ Deck Boards: specially machined fibre cement boards designed for seamless fixing
  • Fast-track fixing system: featuring a double-winged base jointer and a snap-in top strip
  • Coating options: boards can be finished with durable, trafficable paving paint for colour choice or a penetrating clear sealer for a natural look

This system offers a durable, low-maintenance decking solution with a sleek appearance and fast, cost-effective installation.
